Disobstruction of the inferior vena cava under extracorporeal circulation

, : Disobstruction of the inferior vena cava under extracorporeal circulation. Presse Medicale 16(7): 353-354

An original technique used to remove obstructions of the inferior vena cava under cardiopulmonary bypass is described. This technique is indicated in pulmonary embolectomy or to dispose of a vena cava clot prolapsed into the right cardiac cavities. Through a rigid and blunt thoracic drain introduced via the right atrium, a Fogarthy venous catheter is pushed into the inferior vena cava, thus avoiding the risks of accidental passage into the supra-hepatic or renal veins and blockage in a thebesian valve. The catheter is inflated, then removed together with the drain, thereby freeing the caval lumen. The technique is reliable and reproducible, and it has proved very effective.
